I have the same issue dear. My petition is f2B visa too. I have been documentarily qualified since December 2020 and it is in the queue waiting for an interview appointment. My priority date is Jan 5th 2006.
You have to be patient. Right now the visa bulletin for f2B visa is still in July 2015. It's going slow at the moment. Since your priority date is at 2020, I'm guessing it will take Several years before you get scheduled for an interview since they are still dealing with those in 2015.
Btw what year were you petitioned for?
Susu24 got a reaction from HYga in All F2B Updates in This Thread (Part 2)
